A secure image-based authentication scheme for mobile devices

Abstract

Motivated by the need for designing secure and user-friendly authentication method for mobile devices, we present a novel image-based authentication (IBA) scheme in this paper. Its mnemonics efficacy rests on the human cognitive ability of association-based memorization. To tackle the shoulder-surfing attack issue, an interactive authentication process is presented. System performance analysis and comparisons with other schemes are presented to support our proposals. © Springer-Verlag Berlin Heidelberg 2005.
